Audi 8Y RS3 Sportback Fi Exhaust (Frequency Intelligent Exhaust) high-performance valvetronic exhaust system is direct replacement bolt on system manufactured out of a high-grade T304 stainless steel that offers an exhilarating soundtrack.

The Fi EXHAUST system is designed with a valvetronic technology to control airflow, sound volume and enhance the overall performance and torque. On average horsepower is expected to increase from 5-10% after installing a full catless system, which includes a valvetronic catback and ultra-high flow downpipe.

When valves are closed exhaust gasses are routed through the muffler resulting in a low-profile comfortable drive. However, when the valves are fully open an intense and sporty soundtrack is produced.

Depending on your car model and exhaust setup, switching exhaust valves between street and race modes may be achieved using a factory exhaust/sport button, drive modes, or by selecting the Fi Pro remote control upgrade. Please note that not all options are available for every model. Refer to the available section and contact our representative for confirmation.

The unique sound and performance for Audi 8Y RS3 Sportback is achieved through individually designed muffler internals that are fabricated to offer an ultimate driving experience.

Please note each part of the Fi EXHAUST system needs to be ordered separately.
Different exhaust parts are offered depending on the vehicle version.

Please note that the actual product may vary in appearance depending on the year of the car and area. The exhaust system is also subject to changes to the design over an extended time period. Product pictures are for illustration purposes only.

Great
I recently used this motor oil for my car, and I’m very satisfied with the results. The engine runs smoother and quieter, and I noticed improved performance almost immediately. It provides excellent protection, especially during longer drives, and helps maintain steady engine temperature.

Amazing Spark plugs
Smooth starting came after I fitted these Bosch 9614 double iridium plugs into my 2014 Honda Accord Sport, along with slightly better idling behavior. Longevity might come from those fine iridium tips; installing them felt straightforward enough. Yet here's the catch - the 9614 doesn't match what the factory actually specifies for the 2.4L engine in that year’s Accord. Most often, it's the 9694 or some other OEM-recommended plug you’d want instead
